摘 要

本次毕业设计的题目为《9000吨多用途船动力装置设计》，主要是根据给出的船舶的初始参数，来进行船舶的动力装置设计。所谓船舶的动力装置，包括主推进装置、辅助推进装置、辅助机械、船舶管系等。而动力装置设计的重中之重就是船舶、主机和螺旋桨之间的匹配，这将影响整个船舶的方方面面。在这个为基础下，就该考虑其他因素，如船舶的美观性，航行的经济性、船员的舒适性已经对环境的污染问题。

本次毕设，根据已知的初始数据，完成一系列的任务。第一为主机型号的选择：首先进行了船舶阻力的估算，然后利用爱尔法预估出了船舶的有效功率，最后根据螺旋桨的半径假定转速画出图表估算出了螺旋桨最佳转速和其所匹配的主机型号；第二为其他机械设备的型号选择：这主要是根据预估的主机来进行匹配，具体数据皆来自参考文献或者网络；第三把所有设备数据进行整理，制成设备明细表；第四根据初步估算出的所有设备，进行机舱布置，并利用CAD制图软件，绘制出相对应的机舱布置图，同时也要对燃油、滑油和冷却水等系统，进行管系的原理布置，绘制其管系原理图。

现如今的科技发展，人类对海洋的开发力度越发的强，海洋运输也成了各个国家直接贸易的主要型式，船舶的发展也是必然的，船舶必将越发的科学，同时也应该更加的环保。通过这次的毕业设计，深深的觉得我们国家在船舶设计这方面还有很长的路要走，世界在船舶设计方面也还需要更多的创新。无论是能源的利用还是结构的设计都不尽完美，还需越来越多的人才去贡献自己的力量。

通过本次毕业设计，我更加的了解一艘船的由来，更深刻的理解船舶各部分的配合。在当今飞速发展的社会下，唯有创新才能更好的跟上时代的脚步，唯有环保才能有更多美好的未来。

Abstract

The topic of this graduation design is lt;9000 ton multi-purpose ship power plant design gt;, is mainly based on the initial parameters given by the ship, to design the power device of the ship. The ship power plant, including the main propulsion device, auxiliary propulsion unit, auxiliary machinery, ship piping system. And the design of power device of heavy the ship is, matching between the host and the propeller, it will affect the entire ship aspect. On this basis, should consider other factors, such as the appearance of the ship, economy of sailing, the comfort of the pollution to the environment.

The design, according to the initial data of the known, complete a series of tasks. The first is to choose the type of host: first of all, the estimation of ship resistance, and then estimate the effective power of the ship by Irish law, according to the assumption of draw speed propeller radius chart to estimate the optimal speed of propeller and its matching the type of engine; second, other machinery and equipment type selection: This is mainly based on the estimated host to match specific data from references or network; third all the equipment data, make equipment list; fourth according to a preliminary estimate of all equipment, engine room arrangement, and Using CAD mapping software, draw the corresponding engine room layout, but also to fuel, lubricating oil and cooling water system, piping system principle layout, draw its pipe system principle diagram

Now the development of science and technology, more and more strong efforts to develop human beings on the oceans, marine transportation has become the main type of various countries direct trade, marine development is inevitable, the ship will become more scientific, but also should be more environmental protection. Through this graduation design, the design of our country has a very long the way to go in the ship feel deeply, the world in ship design also needs more innovation. Whether the design of the use of energy or structure are not perfect, still need more and more talents to contribute.

Through this graduation design, I know more about the origin of a ship, the ship part of understanding more profound. In the rapid development of the society, only innovation can better keep pace with the times, only the environmental protection can have more beautiful future.
